交叉参考
本申请案主张2019年3月21日申请的第62/821,771号美国临时专利申请案的优先权，其内容以引用的方式完全并入本文中。
技术领域
本申请案大体涉及电子封装的外壳及相关联设计特征。特定来说，本申请案涉及涉及用于(例如)悬挂式天花板中的天花板安装式电声组件(例如阵列麦克风)的外壳及相关机械及装饰设计特征。
背景技术
会议环境(例如会议室、视频会议情境及类似者)可涉及使用麦克风来从音源捕获声音，及使用扬声器来将捕获的声音散布到环境中的听众、电视广播、网络广播等。音源可包含(例如)人类演讲者。
在一些环境中，麦克风及/或扬声器可放置于靠近音源的桌或讲桌上以便捕获声音。然而，此类麦克风及扬声器归因于其大小及/或其中使用所述麦克风的环境的美观而可为突兀或不合意的。另外，放置于桌上的麦克风可能检测到不合意噪音，例如敲笔或翻页。放置于桌上的麦克风还可例如被纸、布或餐巾覆盖或遮挡，使得声音无法恰当或最佳地被捕获。
在其它实施例中，麦克风可包含枪式麦克风，其主要对一个方向的声音敏感。枪式麦克风可经定位远离音源，且可经引导以通过使麦克风指向由特定音源占据的区域而检测来自所述音源的声音。然而，确定指向枪式麦克风的方向以最佳地检测来源于其音源的声音可为困难且乏味的。可需要试错法来针对来自音源的声音的最佳检测调整枪式麦克风的位置。因而，无法理想地检测来自音源的声音，直到恰当地调整麦克风的位置。且即便如此，如果音源在麦克风的拾取范围内外移动(例如，如果人类演讲者在说话时移动他/她的座位)，那么音频检测可能非最佳。
在一些环境中，麦克风及/或扬声器可安装到会议室的天花板或壁以空出桌上空间且使人类演讲者能够在室内自由移动，借此用桌上及枪式麦克风解决至少一些上述问题。在一些天花板安装式麦克风或扬声器设计中，可期望将麦克风或扬声器直接安装到天花板或悬挂在天花板上。在其它设计中，可期望利用现存悬挂式天花板格架来安装麦克风或扬声器。此外，虽然天花板麦克风鉴于其远离桌而无法拾取桌上噪声，但此类麦克风归因于与扬声器及HVAC系统的更近近接性、距音源更远及对空气运动或白噪音的增加敏感度而具有其自身的拾音困难。且在其中天花板麦克风安装于悬挂式天花板格架内的情形中，存在起作用的其它因素，例如，例如各种建筑法规或认证要求，及与各种安装配置及壳体设计相关的麦克风性能/质量变量。
因此，尤其允许取决于特定安装或环境的安装及性能考虑中的灵活性的设计可行。

在一些实施例中，所述外壳进一步包括界定所述天花板阵列麦克风的外围边界的框架元件，所述安装元件经进一步配置以附接到所述框架元件。
在一些实施例中，所述外壳进一步包括安置于所述唇缘部分下方的后部部分，所述安装元件邻近于所述后部部分附接到所述框架元件。

具体实施方式
以下描述描述、说明且示范根据本发明的原理的本发明的一或多个特定实施例。此描述并非被提供来将本发明限制于本文中描述的实施例，而是用来说明且教示本发明的原理，使得所属领域的一般技术人员能够理解这些原理，且运用所述理解能够应用所述原理以不仅实践本文描述的实施例，而且实践根据这些原理可想到的其它实施例。本发明的范围希望涵盖在字面上或根据等同原则可落在所附权利要求书的范围内的全部此类实施例。
应注意，在描述及图式中，相似或基本上类似元件可用相同元件符号标记。然而，这些元件有时可用不同数字标记，例如(举例来说)在此标记有利于更清楚描述的情况中。另外，本文中陈述的图式不一定按比例绘制，且在一些例子中，比例可已经夸大以更清楚描绘某些特征。此类标记及图式实践不一定暗指潜在实质目的。如上文所述，本说明书希望被视为整体且根据如本文中教示的本发明的原理解释且为所属领域的一般技术人员理解。
本文的公开内容涉及声电装置(例如麦克风、麦克风阵列、波束成形麦克风阵列、扬声器、扬声器阵列及类似者)的外壳、机械封装及安装以及设计概念。本文描述且说明的许多实施例涉及天花板阵列麦克风，但应理解，一些概念及其它原理可相对于其它装置及电子封装及其它形状因子应用，且因而，此公开内容不应如此限制。为便于参考且说明，以下描述指代天花板麦克风阵列，理解所述概念及原理也可适用于其它装置。
参考图式，图1及2分别是根据本文描述的本发明的一或多个原理的天花板阵列麦克风10的实施例的顶部及底部透视图。如展示，天花板阵列麦克风10包括外壳12且充当麦克风阵列的相关联电气、声学及电声组件的电子封装。此类组件可包含(例如)一或多个PCB、电子安装设备或底架、麦克风(例如，例如MEMS麦克风)、控制器、混音器、连接器端口等。麦克风阵列可包含一或多个处理器，且可包含例如通道选择、波束成形、混音、每通道或混音后声学回声消除(AEC)的功能，或与麦克风产品(例如波束成形麦克风阵列)相关联的其它功能。在一些实施例中，天花板阵列麦克风还可并入一或多个扬声器。
如本文使用，且为便于参考，“顶部”或“后部”指代将面向悬挂式天花板的内部空间(即，下降空间)的天花板阵列麦克风的部分。相反地，“底部”或“前部”指代将面向具有悬挂式天花板的房间的内部空间(即，房间空间)的天花板阵列麦克风的部分。如在图2中展示，外壳12进一步包括具有前表面16的前面板14，所述前表面16允许声能通过到容置于外壳内的麦克风。在一些实施例中，面板14可具有穿孔或其它孔隙(例如金属或塑料筛网或盖，或具有多孔或半多孔性质的布或发泡体材料)。呈框架形式的安装元件18安置于外壳的外围周围。安装元件18包含在天花板阵列麦克风10安装于悬挂式天花板的格架系统内时使用的唇缘部分20，如本文将进一步描述。参考图1，外壳12进一步包括具有后表面24的后面板22。在一些实施例中，后部外壳26安置于后表面24上，所述后部外壳26为例如一或多个处理器、端口等的组件提供进一步封装空间。
如从图1了解，安装元件18具有突出部分28，如在图3中说明，当天花板阵列麦克风经由安装元件18的唇缘部分20安装于格架系统内时，所述突出部分28允许天花板阵列麦克风10的外壳12的其它部分延伸远离周围悬挂式天花板，且突出到内部房间的空间中。取决于房间特性、安装及其它变量及需求，此特征可提供天花板阵列麦克风的更好性能。另外，此特征可针对特定建筑法规或认证提供益处。例如，特定法规或认证(例如消防法规或UL认证)可需要特定设计参数，例如，例如安装于悬挂式天花板中的任何电子设备经安装，使得任一部分都不定位于天花板的通气部或下降空间内。此配置还消除通气部或下降空间中的阻碍，否则所述阻碍可干扰配管、HVAC管道、电导管或通气部或下降空间内的其它组件。另外，如从图3了解，外壳的突出设计允许天花板砖(ceiling tile)仍安装于格架系统29(其中安装天花板阵列麦克风10)中，此可有利于通过消除将绝缘或纤维毡放置于天花板阵列麦克风的后部上方的需要而满足特定消防法规或其它要求。
如在图4中展示，天花板阵列麦克风10凭借安装元件18向下突出到房间中。安装元件18可以各种形状、大小及尺寸配置，如将在本文中描述。可相应地配置突出量。在实施例中，安装元件18包含边框元件30，所述边框元件30如将描述那样尤其提供前面板14的附接。在其它实施例中，一或多个外壳组件可具有一体式设计。例如，安装元件18可与天花板阵列麦克风的前面板14或后面板22集成。另外，应注意，虽然前面板14及后面板22被展示为相对平坦的面板状结构，但这些组件还可采取例如盒状形状或其它几何形状的形状因子，此取决于天花板阵列麦克风的外壳的形状因子。在所展示的实施例中，突出部分28具有围绕外壳12的外围的实心连续性质，使得当安装天花板阵列麦克风时，在从房间内观察时无到下降空间的间隙或视线。此提供美观的安装。
参考图5及6，在一些实施例中，安装元件18经配置为机械紧固到后面板22。如在图5中展示，安装元件18包含边框元件30中的狭缝32，所述狭缝32经配置以在组装时接合前面板14的边缘部分32。弹性部件34可设置于狭缝32内，如在图5中展示，此尤其抵消与组装公差堆叠相关联的任何问题。弹性部件34可由任何弹性材料(例如发泡体、橡胶或其它弹性体材料)制成。
图7及8展示安装于悬挂式天花板系统的格架系统29内的天花板阵列麦克风10。如在图7中展示，凭借安装元件18，天花板阵列麦克风突出到其中安装悬挂式天花板的房间中。安装元件18的尺寸可经配置以确定到房间中的突出量。此取决于应用及不同环境特性可为有利的。在一些实施例中，安装元件18是可移除的且可与具有各种尺寸的其它安装元件交换。此将允许集成者或安装者定制安装。
如在图8中展示，安装元件18的唇缘部分20经配置以接合格架系统29的格架部件42的面板表面40。在所说明的实施例中，唇缘部分20搁置于面板表面40上。在一些实施例中，安装元件18的唇缘部分20围绕天花板阵列麦克风的外围连续，借此由格架系统大体连续围绕所述外围支撑。在其它实施例中，唇缘部分20可经配置为天花板阵列麦克风的外围周围的间隔部分。图9展示安装于格架系统29内的天花板阵列麦克风10的横截面视图。图9说明天花板阵列麦克风10与周围天花板砖50之间的大体尺寸及空间关系，例如含有天花板阵列麦克风10的电子设备及麦克风的外壳12的部分的下降位置。如说明，后部外壳26在由周围天花板砖的内部房间表面52形成的平面下方。在一些实施例中，后部外壳26将在周围天花板砖的内部表面54处或下方。
图10及11说明其中安装元件62与框架元件64分离的天花板阵列麦克风60的另一实施例，其中框架元件64界定具有弯曲、线性或曲线轮廓的外围边界。此配置在提供数个装饰形状及设计方便提供灵活性。在图11中可见具有框架元件64的天花板阵列麦克风60的总体视觉外观。在其它实施例中，安装元件62可与框架元件64成一体。如在图10中说明，安装元件62可附接到天花板阵列麦克风的后部部分66。在所说明的实施例中，安装元件62可经由一或多个机械紧固件68通过机械紧固附接到天花板阵列麦克风的后部部分66。还考虑其它紧固方法，例如粘合剂、焊接或摩擦配合。如在图12中展示，天花板阵列麦克风60及安装元件62经配置使得含有电子设备及麦克风的天花板阵列麦克风60的部分定位于安装元件62的唇缘部分70下方，使得当安装于天花板格架系统中时，所述部分将定位于由周围天花板砖的内部房间表面形成的平面下方。在一些实施例中，天花板阵列麦克风可经配置使得在被安装时，含有电子设备及麦克风的天花板阵列麦克风60的部分在周围天花板砖的内表面处或下方。
图13及14展示具有曲线形状的安装元件80的另一实施例的轮廓及透视图。如说明，安装元件80及框架元件82一起产生曲线形状因子。应理解，考虑许多其它线性、弯曲、曲线及其它几何形状以在被并入如本文考虑的天花板阵列麦克风中时提供许多可能的装饰形状及设计。还应理解，安装元件80及框架元件82可具有一体式设计。
图15及16展示其中托架90附接到天花板阵列麦克风96的外壳94的后部部分92的又另一实施例。在此实施例中，托架90包含多个延伸部98，其各自具有经配置以接合格架系统104的格架部件102的面板表面100的唇缘部分99。再次，如同其它实施例，托架90定位天花板阵列麦克风，使得含有天花板阵列麦克风96的电子设备及麦克风的外壳94的部分定位于由周围天花板砖122的内部房间表面120形成的平面下方。
图17及18进一步说明将天花板阵列麦克风96安装于格架系统104内。托架90可经由紧固件或粘合剂机械紧固到外壳94的后部部分92，且在一些实施例中，托架90可与外壳94的一部分一体成型。参考图15及16，可见，外壳94与周围天花板砖122之间存在一间隙，所述间隙在一些观看角度允许房间内的人看到悬挂式天花板的下降空间。因此，如果这是不合意的，那么一些实施例可部署实心托架使得不存在到下降空间的开口。在其它实施例中，可在托架90上方放置盖或天花板砖以实现相似结果。
还考虑，托架90可用于将延伸柱(未展示)的一个端附接到其，取代直接附接到天花板阵列麦克风。延伸柱的相对端可附接到天花板阵列麦克风。在此实施例中，延伸柱将提供天花板阵列麦克风到内部房间空间中的进一步突出。延伸柱可为通常用于天花板投影仪或类似者的现成类型的柱，或其可针对本文考虑的应用特殊设计。虽然通常具有圆柱形形状，但延伸柱可采取任何数目个形式，例如矩形或杆状、I型梁形状，或甚至可为(例如)电缆或导线。在一些实施例中，延伸柱及托架可用凸轮锁类型附接系统配置，其中延伸柱的端具有接合托架中的对应一或多个狭缝或突出部的一或多个狭缝或突出部，使得当柱的端与对应狭缝或突出部配接时，其可被扭转到接合位置。还考虑，此安装配置还可被直接并入天花板阵列麦克风的外壳中以直接安装到托架，使得天花板阵列麦克风可直接凸轮锁定或扭转锁定到托架。还考虑柱/托架及柱/麦克风附接两者可为凸轮型或扭转锁定附接配置。
图19以部分横截面展示又另一实施例，其说明天花板阵列麦克风130的又另一曲线轮廓。如展示，安装元件132与框架元件134分离，其中框架元件134界定具有弯曲、线性或曲线轮廓的外围边界。安装元件132提供进一步轮廓上下文且可具有弯曲、线性或曲线轮廓。此配置在提供许多装饰形状及设计方面提供灵活性，同时仍起作用以将天花板阵列麦克风安装于悬挂式天花板的天花板格架系统内。安装元件132经配置为具有凸缘或唇缘部分133，所述凸缘或唇缘部分133接合天花板格架的表面以用于安装于悬挂式天花板内。
在图20及21中可见具有安装元件132及框架元件134的天花板阵列麦克风130的总体视觉外观。在其它实施例中，安装元件132可与框架元件134成一体。如在图19中说明，安装元件132可附接到天花板阵列麦克风的支撑部件136。此附接方案允许安装元件132更明显朝向天花板阵列麦克风130的中心向内弯曲，同时仍在安装配置中提供充分的刚性及支撑。附接可通过机械紧固件实现，例如螺丝137、或粘合剂、焊接、摩擦配合或技术中已知的任何其它附接方法。如在图21中展示，支撑部件136安置于天花板阵列麦克风130的每一大体边角处，但应理解，还考虑其它支撑结构，例如围绕天花板阵列麦克风的大体外围安置的连续或间隔框架部件，或利用其中安装元件132直接附接到其或与其一体成型的天花板阵列麦克风的外壳的后部表面。
此公开内容希望解释如何根据技术塑造且使用各种实施例而非限制其真实、预期及公平的范围及精神。以上描述并不希望是穷尽性或限于所公开的精确形式。鉴于上文教示，修改或变化是可能的。选择且描述(若干)实施例以提供对所描述的技术的原理及其实际应用的最佳说明，且使所属领域的一般技术人员能够在各种实施例中且以合适用于所设想特定用途的各种修改利用本技术。当根据其被公平、合法且公正地赋予的宽度来解释时，所有此类修改及变化是在如由所附权利要求书(其可能在本专利申请案的待审期期间被修订)及其等效物确定的实施例的范围内。
